•85, 78, 80, 108, 46, 66, 68, 82, 72, 68
Answers
They all have a minimum of 46 and maximum of 108. The median is 75 and since there's 10 numbers in each set, you would have to find the middle of two numbers.
First set:
Let's put them in order.
46, 66, 68, 68, 70, 70, 80, 82, 85, 108
The median of that set is 70, not 75.
Second Set:
Let's put them in order.
46, 66, 68, 68, 72, 78, 80, 80, 85, 108
Right away, I can tell the median of the set is 75. We should still check the other sets.
Third set:
Let's put them in order.
46, 66, 68, 72, 78, 80, 80, 82, 85, 108
Fourth set:
Let's put them in order.
46, 66, 68, 68, 72, 78, 80, 82, 85, 108
So, the fourth and second set both have a median of 75. We need to find their third quartile. On the graph, it is about 82 or 83.
Second Set's third quartile: 80
Fourth Set's third quartile: 82
So the box plot represents the last set of numbers.

Samantha measured two of the angles in PQR and found that they had measures of 65° and 70°. Then, she measured two of the angles in XYZ and found that they had measures of 65° and 45°. What statement best describes the two triangles?
Answers
The angles of a triangle sum to 180°. Using the known angles in the first triangle, we find the missing angle measure:
180-(65+70) = 180-135 = 45
We do the same for the second triangle:
180-(65+45) = 180 - 110 = 70

No more than 8 books are in your bag
Answers
if number of books is x,
then
x≤8.
It says "No more than 8 books are in your bag". Here "Not more than" a specific number would be a set of all values that are "less than or equal" to given number.
So let's consider 'n' represents the number of books in the bag and we know this number can not be a negative value i.e. n is "greater than or equal" to 0.
Also n is "less than or equal" to 8 as given in the question.
Hence, the inequality would be 0 ≤ n ≤ 8.
a circle has an area of 81 3.14 units . what is the diameter in terms of 3.14a circle has an area of 81 Pi square units what is the diameter of the circle
Answers
A circle has an area of 81 3.14 units . what is the diameter in terms of 3.14?
I'd prefer you write this as
"A circle has an area of 81 pi units . what is the diameter in terms of pi?
Area of a circle = A = pi*r^2. Note that r= diameter / 2. Here, the area is 81 pi square units, or 9^2 * pi square units, which means that the radius is 9 units. The diameter is then 2(9 units) = 18 units.
Your second question, separated from the first, is:
"a circle has an area of 81 Pi square units what is the diameter of the circle?"
Use the following formula or formulas: d = 2*r; A = pi*r^2; A = pi*(d/2)^2. Find r first, and then find d.
Answer:
18 units
Step-by-step explanation:
[tex]\pi r^2=81\pi[/tex]
Solve for [tex]r[/tex]:
[tex]\pi r^2=81\pi \\r^2=81\\r=9[/tex]
Knowing diameter is 2*r, we can apply the formula to find diameter
[tex]d=2*r\\d=2*9\\d=18[/tex]
a number cube is rolled 24 times.how many times will a number be less than tree be expected to be rolled?
Answers
it should be 4 out of 24 times
The number of the times cube is rolled for getting less than three is 8.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability of getting less than three = 2 / 6 = 1 / 3
The number of the times cube rolled is,
Pn = ( 1 / 3 ) x 24 = 8
Therefore, the number of the times cube is rolled for getting less than three is 8.

Every shirt she grabs, will cost her dollars, so if she grabs 3 shirts, then the cost of the shirts is:
[tex]12+12+12=3(12)[/tex]
With the same rationale, if she grabs 2 pairs of jeans, the cost of the jeans is:
[tex]19+19=2(19)[/tex]
So, her total is:
[tex]3(12)+2(19)[/tex]
If you subtract 3 from the total, then the expression is:
[tex]3(12)+2(19)-3=36+38-3=71[/tex]
For the second part:
If she's paying 3 less for each shirt, then the cost of 3 shirts will become:
[tex](12-3)+(12-3)+(12-3)=3(12-3)[/tex]
In the same fashion, for the two jeans:
[tex](19-3)+(19-3)=2(19-3)[/tex]
So the expression for the total cost is:
[tex]3(12-3)+2(19-3)=36-9+38-6=59[/tex]
For number three:
The amounts are different because the cost of the total purchase is different than the cost of each element that makes up the total purchase.
For number four:
If you're the owner, you want to give the smallest amount of discount (the one in part 1/a).
So you could clarify by saying there's 3 dollars of the TOTAL purchase's cost.

Answer:
[tex]( \frac{36n^{2} }{25} - 1) [/tex] factors to become [tex]( \frac{6}{5}n - 1)( \frac{6}{5}n + 1) [/tex]
Explanation:
The binomial [tex]( \frac{36n^{2} }{25} - 1) [/tex] is what is called a difference of two squares which can be identified by the equation being in the form (a² - b²) where both terms can be square-rooted.
Because the equation is a difference of two squares, its factors will be in the form: (a - b)(a + b).
With a² = [tex]\frac{36n^2}{25}[/tex] and b² = 1, we can find the square root of both and plug them into the above factor form.
√(36n² / 25) = 6n/5
√1 = 1
So the factors are [tex](\frac{6}{5}n -1)(\frac{6}{5}n +1)[/tex]

Answers
Answer: 537
Step-by-step explanation:
Given: a = 640 A =70° B =52°
Whenever two angles and one side of a triangle is given, we can always use the sine formular to find the other side
Using the sine formula;
sin A / a = sin B /b
sin70° / 640 = sin 52° / b
cross multiply
bsin70° = 640sin52°
To get b, we divide bothside by
sin 70°
b = 640sin52° / sin 70°
b = 504. 327 / sin70°
b = 536. 693
